General Information | Comment | Organism |
---|---|---|
physiological function | lysyl hydroxylase 3 (LH3) is a post-translational modification enzyme with lysyl hydroxylase, collagen galactosyltransferase EC 2.4.1.50, and glucosyltransferase, EC 2.4.1.66, activities, LH3 is able to catalyze the three consecutive reactions required for the formation of unique hydroxylysine-linked carbohydrates, galactosylhydroxylysine and glucosylgalactosyl hydroxylysine, found in collagens and a few other proteins. The active sites for the different activities of the mutifunctional enzyme are localized separately in the C- and the N-terminal parts of the molecule. While the lysyl hydroxylase active site mediates retention of LH3 in the endoplasmic reticulum, the glucosyltransferase active site is required for the secretion of LH3 into the extracellular space | Canis lupus familiaris |
